Floating Offshore Wind
A new generation of energy in the Celtic Sea
Harness More Wind
Almost 80% of the world’s wind resource is in water deeper than 60 metres
Less Visual Impact
Floating wind is further offshore meaning less visual impact and reduced conflict with other marine users
Meet Emissions Targets
Needed to meet the UK’s net-zero emissions targets and deliver on ambitions set by the Climate Change Committee
Opening up a whole new world of offshore renewables
The International Energy Agency estimates that floating wind turbines could help provide enough electricity to satisfy the world’s electricity needs 11 times over.
It is estimated by the ORE Catapult that the first GW of floating wind in the Celtic Sea could potentially deliver over 3,000 jobs and £682m in supply chain opportunities for Wales and Cornwall by 2030.
Studies suggest there is up to 50GW of attainable wind resource in the Celtic Sea.
A new energy partnership
Simply Blue Energy, an offshore wind project developer, and TotalEnergies, one of the world’s largest energy companies, have established a partnership to develop floating wind project in waters of the Celtic Sea. The joint venture, Blue Gem Wind was announced in March 2020 and opens a new chapter in the development of offshore energy in the UK.
Erebus – A 100MW demonstration project
Erebus is a 100MW demonstration project 35 km offshore. The project, named Erebus after the famous ship built in Pembroke Dock is anticipated to be the first floating offshore wind project in the Celtic Sea.
Erebus is one of the most advanced test and demonstration projects in the Celtic Sea, set to be delivered towards the end of the decade, ahead of commercial-scale developments under Leasing Round 5. It will help build capability within the local supply chain and prepare the region for the large-scale projects expected in the 2030s.
